UNITE S'ra'rns EDI/YARD BLOUNT, OF SMITHS MILLS, SOUTH CAROLINA-CARRIAGE=AXLE.

SPECIFICATION forming part of Letters Patent No. 306,214, dated October7, 3884.

Application filed April 8, 1884. (No model.)

To aZZ whom it may concern Be it known that I, EDWARD BLoUN'r, a citizenof the United States, residing at Smith s Mills, in the county of\Villiamsburg and State of South Carolina, have invented certain new anduseful Improvements in Axles; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the artto which it appertains to make and usethe same.

This improvement relates to axles that are made separately from andaffixed to the main axle-trees, and has for its object a more practicaland strongly constructed axle than others of its class, that can also bemade to equal ize or compensate for wear by adjustment of some of theparts. These results are attained by the mechanism illustrated in thedrawings herewith filed as part hereof, in which the same letters ofreference denote the same parts in all the views. 7 V

Figure 1 is a view of my improvement, partly in section. Fig. 2 is a topView, part broken away. Fig. 3 is a front end elevation. Fig. 4 is aportion of the mairi'axle-tree. Fig. 5 is a vertical section of one ofthe parts detached. Fig. (5 is a view of one of the minor parts.

A represents an axle-tree proper, provided with a shoulder, a, and ahollow or cylindrical screw threaded extension, A, as speciallyillustrated in Fig. 4C, and which is provided with a female screw-threadwithin the recess thereof.

B represents the wheel-axle journal, which is provided with ascrew-threaded shoulder, B, and a screw-threaded reduced extension, B,corresponding to the female thread within the hollow extension A of theaxle-tree A.

G c 0 represent a sleeve for strengthening the joint formed by theaxle-journal and axletree, and is provided with an inner threadcorresponding to the thread and the shoulder B of the axle-journal B,and the thread on the extension A of the axle A.

D is a lock-nut for locking the position of the sleeve, which at itsenlargement O is made of octagonal form for convenience of adjustment.The lock -nut D is of similar form. The sleeve is reduced at c for thepurpose of entering the usual recess in the boxing of the wheel andbeing set to bear against the shoulder thereof, and thereby preventunnecessary and injurious lateral motion of the wheel. The sleeve isprovided with recessed and screwthreaded projections G, for thereception of set-screws G for additionally securing the sleeve in anydesired position.

1) represents the usual loclcnut at the end of the axle.

All the different threads should be made to screw up in the samedirection on the same side, and on each side the direction of thethreads must be arranged according to the forward motion of the vehicle.By setting a washer of suitable thickness between the locknut and thesleeve, or between the lock-nut and the shoulder of the axle-tree A, thesetscrews 0 may be dispensed with. By this construction the axle-journalcan be made of the best material, while the axle-tree may be made ofordinary metal, and in addition to thus obtaining an axle of superiorquality the same can be easily removed and conveniently replaced byanother should the axle get bent or broken, which is frequently the casefrom various causes.

Having explained the construction and operation of my improvement, whatI claim as new, and desire to secure by Letters Patent, 1s-

The axle journal or spindle B, having screwthreaded shoulder B andreduced screwthreaded extension B, in combination with the axle-tree A,having shoulder a and hollow screw-threaded extension A, the sleeve 0 co, and the lock-nut D, all constructed and arranged to operatesubstantially as specified,

for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
